HEEL-FINISHING MACHINE.

SPECIFICATION forming part of Letters PatentNo. 743,993, dated November10, 1903. Application filed March 25, 1902. Serial No. 99,851. (Nomodel.)

To all? whom it may concern:

Be it known that I ROBERT W. THOMSON, of Lynn, county of Essex, andState of Massachusetts, have invented an Improvement in' Heel-FinishingMachines, of which the following description, in connection with theaccompanying drawings, is a' specification, like characters on thedrawings representing like parts.

This invention has for its object the pro-' duction of an improvedmachine for finishing heels, said machine being constructed and arrangedto apply a hard wax to the heels.

In accordance with this invention I employ any usual or suitableform ofcloth wheel or cloth-covered wheel orother flexible non-inetallicwork-rubbin g wheel which is constructed with a convex yieldingheeLengaging rim, many such wheels being already well known, and providemeans for applying wax to the heel engaging rim of said wheel and forspreading the wax thereon. Preferably the wax-spreading means is heated,so as to assist in maintaining the heel-engaging rim of said wheel at atemperature sufiiciently high to keep the wax thereon in moltencondition while it is being applied tothe heel and for shaping theheel-engaging rim of said wheel.

In practice the heel is held pressed against the work-rubbing wheel withconsiderable pressure,and this resultsin flattening the convex rim ofthe wheel, which for the best results should be restored to its originalshape, so that the portion of the rim acting on the heel shall alwayspresent a convex surface.

The necessity for providing means for acting on the rim of the wheel forrestoring it to proper shape is rendered greater by reason of the rimbecoming saturated with the is a vertical section of the machine shownin Fig. 1, taken on the dotted line 2 2.

Fig. 3 is a vertical section of the heated roll and waxapplying deviceshown in Fig. 2. Fig. 4 is a detail of the means shown in Fig. 2 formoving the heated roll out of engagement with the work-rubbing wheel.

In the embodiment of the invention herein shown, it represents aflexible non-metallic work-rubbing wheel or roll, which is here shown asa cloth wheel or cloth-covered wheel, and 0, represents a shaft to whichthe work rubbing wheel is secured.

11 represents an idle roll which is loosely mounted on a bar I) anddisposed relatively to the work-rubbing wheel to bear upon itsheel-engaging rim. The roll 19 has an annular recess h? in one or bothof its sides, which provides for the employment of suitable gasburners19 by means of which said. roll is heated.

form of heel-engaging rim, the heated roll 3) will be formed with acircumferential groove or recess 19 of a corresponding shape in orderthat it may snugly embrace the wheel.

The heated roll, shaped as described, acts on the wax-saturated rim ofthe work-rubbing wheel, heating said rim and molding it in accordancewith the face of the heated roll, thereby efiectually restoring said rimto its original form.

The shaft or bar bearing the heated roll I) is held in suitable bearingsin a movable frame, which is herein shown as comprising a pairof arms bsecured to a shaft b held in suitable hearings in the frame of themachine,

The shaft b has an arm Z9 projecting from it, formed with an inclinedsurface which is engaged by a friction-roll b borne by a lever I7pivoted at b, said lever extending forward within easy reach of theoperator.

sition to the dotted-line position in Fig. 1

the arm 11 will be depressed and the shaft 39 correspondingly rocked andthe heated roll I) moved out of engagement with the workrubbing wheel.

The lever h has secured to it a yoke,

which serves as the belt-shifting device for the belt I), which drivesthe pulleys 17, mounted on the shaft 0,.

The lever I3 will be moved to shift the belt onto the fast pulley at thesame time that it operates to move the heated roll into engagement withthe work-rubbing wheel and to shift the belt onto the loose pulley atthe same time that it operates to move the heated roll out of engagementwith the workrubbing wheel. It is important to remove the heated rollfrom engagement with the work-rubbing wheel when said wheel is at restto prevent the heated roll injuring the wheel by standing in engagementtherewith.

Beneath the heated roll I; a wax-pot c is provided which is supported bythe frame, and a wax-delivering roll cl is contained in the wax-pot,projecting above the wax-pot into a position to be engaged by the heatedroll I) when the heated roll is in its operative position in engagementwith the work-rubbing wheel a, and as said roll (Z is turned by theheated roll I) it takes from the wax-pot and delivers to the heated roll19 a supply of hot wax, which is transferred by said heated roll to thewheel a. When the heated roll is moved to place it out of contact withthe work-rubbing wheel, it is also removed from engagement with thewax-delivering roll d, as shown in dotted lines in Fig. 2. The waxpot isheated for melting the wax in any suitable manner-as, for instance, by agasflame, as shown in the drawings.

The wax-delivering roll at will be made very narrow, so that but a smallquantity of wax will be supplied to the heated roll I).

In practice the work-rubbing Wheel a will be driven at highspeed, andthe hotwax conveyed to it by the heated roll I) will be ap-- plied tothe heel and rubbed over the surface of the heel.

It will be seen that the heated roll I) not only conveys heated wax tothe work-rubbing wheel and spreads it over the convex surface of thecloth rim of said wheel, but it also heats the said rim, so as to softenthe wax with which it is saturated and mold the rim into its normalconvex shape after it has been flattened out by contact with the heel ofthe shoe being treated. By heating the work-rubbing wheel by means ofthe waxconveying roll, as described, the wax or finishing material onsaid rubbing-wheel is kept hot and in proper condition for the finishingoperation.

Having thus described my invention, I claim as new and desire to secureby Letters Patent of the United States 1.
